With the emergence of a plethora of embedded and portable applications, energy dissipation has joined throughput, area, and accuracy/precision as a major design constraint. Thus, designers must be concerned with both optimizing and estimating the energy consumption of circuits, architectures, and software. Most of the research in energy optimization and/or(More)
Power is considered to be the major limiter to the design of more faster and complex processors in the near future. In order to address this challenge, a combination of process, circuit design and micro-architectural changes are required. Consequently, to focus the optimization efforts in the right direction, the models proposed and studies performed in(More)

Due to ever increasing number of transistors and decreasing threshold voltages, leakage energy consumption is expected to play a decisive role in the next generation circuits. We believe that software support is a must to exploit available leakage control mechanisms. In this paper, we present and evaluate a compiler-oriented leakage optimization strategy(More)
An important problem in extracting maximum benefits from an SDRAM-based architecture is to exploit data locality at the page granularity. Frequent switches between data pages can increase memory latency and have an impact on energy consumption. In this paper, we propose a mathematical formulation, using Presburger arithmetic and Ehrhart polynomials to(More)
Java has become a popular choice for implementing various applications that run on mobile and hand-held devices. Optimizing the energy consumption in mobile environments is of critical importance to prolong the battery life. In this work, we propose an object allocation strategy to reduce the energy consumption of Java applications. This object allocation(More)
In many countries, various in-vehicle Telematics systems are already available, while new systems are being currently designed. This paper introduces a smart roadside server for driver assistance and traffic safety warning. In recent world wide projects, roadside equipment is used for wider applications and becomes a server with more intelligent functions.(More)
